摘要
峨嵋叶蜡石矿储量大,矿石类型主要有石英叶蜡石型、硬水铝石叶蜡石型、叶蜡石型、明矾石叶蜡石型等。各类矿石中的叶蜡石经提纯后,测试结果表明它们分别具有不同的多型,其中石英叶蜡石型为2M_1型,硬水铝石叶蜡石型及青灰色、紫红色叶蜡石型为2M_1+1TC(混合)型,明矾石叶蜡石型为1TC(为主)型。本文在对各类矿石及叶蜡石的多型特征进行较详细论述的同时,还对多型与矿石类型的关系及成因发表了看法。
Emei Pyrophyllite deposit possesses a large amount of reserves with different types of pyrophyllite ore , such as quartz-pyrophyllite, diaspore-pyrophyllite, pyrophyllite and alunite-pyrophyllite etc. The test results of purified pyrophyllite indicate that there are different polytypes of pyrophyllite corresponding to relevant oretypes, such as 2M_1 type for quartz-pyrophyllite, 2M_1+1TC type for diaspore-pyrophyllite and green-gray (or purple-red) pyrophyllite, and 1TC type (mainly) for alunite-pyrophyllite. While discussing polytype characteristics of pyrophyllite in detail, the paper also presents some opinions referring to the genesis and the relationship between polytype and oretype.
